Front passenger airbag deactivation indicator in the instrument cluster
The airbag's functionality is monitored by a warning light that lights up in the instrument cluster, accompanied by a buzzer signal and a corresponding message on the multi-function display.
Turn the ignition key to position "2" ("Ignition on"). If the indicator light comes on and the buzzer sounds, and the message "Front passenger airbag disabled" appears on the display, the front passenger airbag is not operational (i.e., the airbag switch is turned to the "OFF" position).
